POWER-TRANSMITTING MACHINERY.

SPECIFICATION forming part of Letters Patent N 0. 639,879, datedDecember 26, 1899. Application filed July 3, 1899. $erial No. 722,672.(No model.)

To all whom it may concern.-

Be it known that I, EDWIN WINANS, a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Power-Transmitting Machinery, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to and has for its object the improvement ofmachinery by and through which power or force is transmitted from theplace of development to that of its applied usefulness. It is applicableto all swing and crank motions, especially to all of the treadleclass-namely, the bicycle, the sewing-machine, the lathe, the jig-saw,and similar apparatus. It is applicable to the of steam and pressureclass, especially where even and steady crank revolutions are desired.It is applicable to high duty in bicycle presented and described in thedrawings and specification.

A general aim and object of my invention is to ease the labor and motionof an operator in treadling by providing for a full, free, andunhindered up-and-down swing and sway to the whole leg and foot while atwork.

Certain of my improvements consist in the adaptation, combination, andlocation of a plurality of parallel bars or links with operating-leversto assist in the power transmission and passing of centers.

Otherimprovements consistin the construction, arrangement, andcombination of the several parts, portions, or details, as hereinaftershown and described.

Referring to the drawings, Figure l represents an elevation of powertransmitting cranks, connections, bearings, &c., embodying my inventionand improvements. Figs. 2 and 3 represent plan and side views of thesame. Fig. 4 represents a partial elevation of a bicycle provided withapparatus embodying my improvements.

In the several figures of the drawings letter A designates aforce-receiving lever, such force being applied to and received by pin Bthrough the use of treadle, connecting-rod, piston-rod, or similarconnections.

Letter A designates an extension of lever A.

C designates a further extension of the lever A.

D designates an operating-crank attached to shaft F and receiving forcefrom lever A.

Letter E designates main hearing or bearings for crank and shaft.

G designates a fulcrum or swing bearing for a motion-controlling bar H.

Letters L L designate parallel links connecting the controlling-bar Hwith the extension portion 0 of the power, force, or motion receivinglever A.

Letter I designates a transmitting pulley, gear, or sprocket-wheel orequivalent means for efiecting additional or extended power transmissionor speed of revolution.

M designates a bicycle-wheel in disk form with all spokes omitted, theconnections on off side of wheel being dotted for purposes of clearerdistinction. In bicycle practice the power may be taken directly througha chain of gears or sprocket and chain providing for increasedrevolution.

Letter S designates the body framework of a bicycle, andoperating-treadles are shown at B. (See Fig. 4..)

In the operation of the apparatus force is applied at B, throughtreadle, pitman, connection, or similar means, and hence through crank Dto shaft F for use. The continuation A may be long or short, accordingto distance between bearings E and G and the angularity of extension 0with lever A, or its continuation A may vary and must vary according tothe elevated or depressed position of fulcru m-bearing G with referenceto shaftbearing E. In the drawings the fulcrumbearing G is shownslightly higher than shaftbearing E, with consequent angle of O withlever and extension A and A.

What I claim as new, and desire to secure by Letters Patent, is

In combination with a power-shaft and a crank and cranlcpin of saidshaft,a force-receiving lever connecting with and operating saidcrank-pin, an extension of said force-receiving lever beyond saidcrank-pin, a controlling-bar and its fulcrum, and a pair of :00 linksconnecting the said lever extension with the said controlling-bar as andfor the purposes set forth.

EDWIN IVINANS.
